I received the filter kit in reasonable time, all of the parts seem to be there. The installation was realitively straightforward. The only real issue that I had was, it took two people and clamps to close the cover enough to install the 10 nuts and washers. One person could NOT do this alone. I bought this unit because I was frustrated with the difficulty in changing the OEM filter without breaking something. Who knew this would not be much better. At least I won'the have to buy a new filter each time.

I bought the cold air box for my 2006 Ford F350, one year ago. The filter was just taken out for the yearly cleaning. Very nice system. I have seen an increase in mileage on the highway when towing my 5th wheel. Thank you for a great product.

Install on my 2005 Ford F350 6.0 was little over an hour. Biggest issue was the back nut on the back of the KN filter housing below the radiator fluid fill area. Very difficult to get to, but no issues on the install in general. Engine has good response, sound is about the same. Hoping to increase fuel economy but still in the testing process.
